Horizontal Continuous Aluminum Casting and Rolling Machine

Product Description

This equipment adopts a new four-wheel planetary continuous casting machine and continuous casting and rolling process to produce conductive round aluminum rods. The rod diameters produced are Φ12mm, Φ9.5mm, and Φ15mm. The production of Φ12mm aluminum rods uses 13 racks, the production of Φ9.5mm aluminum rods uses 15 racks, and the production of Φ15mm aluminum rods uses 11 racks.

The block diagram of the process flow is as follows:
Holding furnace (prepared by the user) → New four-wheel continuous casting machine → Front traction → Rolling shear → Guide roller device → Continuous rolling mill → Double basket wire take-up machine → Aluminum rod

The four-wheel continuous casting machine consists of upper and lower pouring pots, gravity flow regulating device, crystallization wheel and transmission device, clamping wheel device, steel belt oiling device, approach bridge, tensioning device, ingot picking device, inner and outer cooling device and steel belt.
The molten aluminum flows from the holding furnace through the launder into the upper pot. The gravity-controlled floating plug controls the flow of aluminum into the lower pot. The aluminum is horizontally cast from the lower pot into the mold cavity formed by the crystallization wheel and the closed steel belt. The cross section of the crystallization wheel is H-shaped, and the cooling on all four sides ensures that the ingot crystallization is dense and uniform. Internal and external cooling and side cooling can be easily transferred from the crystallization wheel, which is convenient for cooling water regulation and equipment maintenance; all nozzles are made of stainless steel, and are respectively equipped with cooling water pressure display, cooling water flow regulation, and pneumatic tensioning (adjustable) for steel belt tensioning. An internal cooling device is installed on the supporting shaft of the crystallization wheel. The cooling water with a pressure of 0.2-0.5MPa is sprayed onto the inner surface of the crystallization wheel through the nozzle. There are 4 zones for internal cooling and external cooling, and 2 zones for the inner and outer sides, so that the aluminum liquid is gradually cooled and solidified into aluminum ingots.
The solidified ingot on the crystallization wheel is removed by the ingot remover. The pressing wheel device presses the steel belt tightly against the crystallization wheel to prevent the aluminum metal liquid from leaking out. The guide wheel device is used to adjust and change the direction of the steel belt. The tension of the steel belt can be adjusted by the tensioning wheel device to maintain a certain tension. In order to facilitate the demoulding of the aluminum ingot, the continuous casting machine is also equipped with a steel belt oiling device. Since the whole process is carried out continuously, a long ingot can be obtained.

The rolling shear machine is driven by a motor to drive the reducer to drive the upper and lower cutter discs. The upper and lower cutter discs are each equipped with two cutters. The shearing speed of the knife tip is close to the moving speed of the ingot. The upper and lower cutter discs are both rolling shearing.
When the ingot is drawn out, if the quality of the ingot is not good, the rolling shear will work to cut the ingot into short pieces.
When the ingot meets the rolling conditions, the rolling shear stops working and the ingot is rolled. During the rolling process, if the rolling mill or the winding rod fails, the rolling shear automatically starts to cut the ingot into short pieces and drop them into the ingot feeding trolley to be pulled away.
